ing products, and a composition for use in such treatment, 'and the product of such The'invention constitutes an improvement upon certain'prior patents including Sutherland No. 1,539,701, in which oiganic peroxid compounds are employed for the treatment of flour for improving its keeping 10 qualities and baking qualities and for-bleaching the same, and constitutes aniinprovement. by virtue of which theactivity of the peroxidized compounds is I increased and quickened.

stance is used with the peroxidi'zed com pound, which substance is somewhat volatile, and which carries the peroxidized compound with it when it vaporizes, the improvement of the flour and the bleaching thereof is considerably hastened, and on account of the fact that the'benzoyl peroxid or other peroxidized compound is volatili'zed,'during the operation; it is not necessary that the benzoyl peroxid should be ground to. the exceeding small size of particles as-indicated for example in the patents to ,Kroeber Nos. 1,555,805 and 1,565,37 5, and the expense of such fine grinding operation is accordingly avoided.

- In accordance with the present invention the peroxidized compound can be used in a state I of ordinary fine powder.

Some-of the organic substances which-are volatile occunbothin the crystallized condition and the amorphous condition. The

amorphous condition general] is more readi-.

1y volatilethan the crystallize substance, and

' accordingly we prefer to use the volatileusub stance in an amorphous conditionITather than in the crystalline condition. The process can be carried out frequently at room 4 temperature, and with some of the, substances which may be employed, temperatures somewhat above ordinary room temperature "may be found preferable.

For the purpose of more completely exlaining the nature of the invention,'the fol- 1 owing example is given, but the invention is .not restricted to this specificexample, since not only the substances here referred to can Application filed April 5, 1928. Serial No. 267,794,

be employed, but other substances having a like efi'ec percentage of benzoic acid, in an amorphous state were mixed with freshly milled flour from mixed wheat. The mixing was performed at room temperature and the benzoyl peroxid and. benzoic acid were both in the form of powders although not reduced to the Very fine state referred to in the patents to at room temperature for six hours, and it was found that the bleaching of the flour had been lel experiment the same percentage 0 benwas added to the same quantity of the same kind of flour and allowed to stand sixhours.

is a somewhat volatile material, ver greatly accelerated the bleachin of the our, and the improved result is ue," in our opinion, to the fact that the'benzoic acid is somewhat volatile, and involatilizing it carries with it the vapors of benzoyl peroxid, which itself is far less volatile than benzoic acid, but when mixed with benzoic acid, the volatility thereof is substantially increased. 1

While the very fine grinding of the Kroee her patents has been found useful in connection with the use of peroxidizcd compounds, we find that when a somewhat volatile 'substance of the class herein mentioned is employed, the peroxidized substance can be employed in the form of even a relatively coarse.

powder, containing particles up to say one hundred microns in size.

- While we have above referred to' the use of solid peroxidized compounds (including ben- Tzoyl peroxid) liquid peroxidized compounds (including liquid per'oxi'ds) can be used.

Likewise, as the vaporizable substance, solids or liquids can be employed.

We claim 1. A process of treating edible milling products with an organic peroxid-ized com pound which comprises treating sa'idp ucts with a mixture of an organic peroxidized compound m an amorphous state and a substance which increases the rate of 'volatilization ofsaid peroxidized compound, whereby the action of such peroxidized compound,

upon said milling roduct is accelerated.

' 2. A process o treating edible milling products with an organic peroxidized compound which comprises treating said products with a mixture of an organic peroxidized compound in an amorphous state .and a substance which is slowly vaporizable at room temperature, and whlch substance when it volatilizes causes said peroxidized compound to vaporize.

3. In the treatment of flour, meal and other edible milling. products, the herein described process which comprises adding a minute .proportion of an organic peroxidlzed compound and of an organic substance which at room temperature is somewhat volatile, and.

which in volatilizing in the presence of such peroxidized compound causes the latter to also volatilize, and allowing volatilization of such added substances, whereby rapid bleaching an organic peroxidized compound and amorphous benzoic acid, the latter bein capable of inducing volatilization of sai peroxidized compound.

11. A new agent for the treatment of edible milling products which comprises benzoyl peroxid and amorphous benzoic acid.

12. A product comprising an edible milling product mixed with a composition as set forth in claim 9. v

13. A product comprising an edible milling product mixed with a composition as set forth in claim 10.

14. A product comprising an edible milling product mixed with acomposition as set forth in claim 11.

4. A process which comprises mixing an edible milling product with small amounts of an or'ganlc peroxidized compound and amor hous benzoic acid.

5. process which comprises mixing an edible milling product with small amounts of benzoyl peroxid and amorphous benzoic'acid.

6. A process of treating flour and like milling products which comprises the step of mixing the same with benzoyl peroxid and an amorphous substance which is capable of inducing volatilization of the latter.
